$$\frac{\sin{\left(x \right)}}{1} + \cos^{2}{\left(x \right)}$$
sin(x)/1 + cos(x)^2
Detail solution
  1. Differentiate term by term:

    1. The derivative of a constant times a function is the constant times the derivative of the function.

      1. The derivative of sine is cosine:

      So, the result is:

    2. Let .

    3. Apply the power rule: goes to

    4. Then, apply the chain rule. Multiply by :

      1. The derivative of cosine is negative sine:

      The result of the chain rule is:

    The result is:

  2. Now simplify:


The answer is:

The graph
The first derivative [src]
-2*cos(x)*sin(x) + cos(x)
$$- 2 \sin{\left(x \right)} \cos{\left(x \right)} + \cos{\left(x \right)}$$
The second derivative [src]
               2           2   
-sin(x) - 2*cos (x) + 2*sin (x)
$$2 \sin^{2}{\left(x \right)} - \sin{\left(x \right)} - 2 \cos^{2}{\left(x \right)}$$
The third derivative [src]
(-1 + 8*sin(x))*cos(x)
$$\left(8 \sin{\left(x \right)} - 1\right) \cos{\left(x \right)}$$
